Abstract: An apparatus and methods are provided for the communication of a data stream and management of faults in a multipath data network having a protected ring-in-ring network architecture. The data stream is communicated over redundant paths between various nodes located throughout the network. Each node is capable of dropping and inserting data from the data stream before passing it on to the next node. A single transmitter in communication with an intelligent splitter at each node is utilized to simultaneously transmit the data stream over the redundant paths. In the event of a fault over one of the paths in the network, the intelligent splitter manages the operation of the single transmitter so that the data stream is communicated over an alternate path to circumvent the fault.

Abstract: A brake corner module includes a wheel bearing assembly which is configured to be coupled to the steering knuckle of the module without requiring bolts or press fit. An outer ring of the bearing assembly has a flange on one end which engages the knuckle at one end of a bore through the knuckle and a second end which is configured to be deformed to engage the second end of the knuckle bore. The wheel bearing assembly is thus captured within the bore, eliminating the need for press fit or a snap ring to retain the wheel bearing assembly.

Abstract: A wheel bearing assembly for a vehicle has a wheel hub with a spindle that extends axially from the hub. A rolling element bearing is coupled to the hub, over the spindle, and is secured to the spindle by a deformed end of the spindle. The deformed end engages a radially outward facing portion of a lip that extends from an inner ring of the rolling element bearing, such that no radially outward force is exerted on the inner ring by the deformed end.

Abstract: A wheel bearing assembly for a motor vehicle comprises a motor having a shaft and a spindle integral with the shaft. At least one row of bearing balls supports the shaft.

Abstract: A mobile switching center receives a call to a wireless telephone unit and determines if the wireless telephone unit is available to receive calls. If the wireless unit is unavailable, the mobile switching center forwards the call to a wireless service node, preferably immediately and without providing any ring back tone to the calling party. The wireless service node prompts the calling party to speak a message for transmission to the wireless telephone unit. The wireless service node converts the message spoken by the calling party from a speech message to a text message and forwards text message to a short message service center for transmission to the wireless unit.

Abstract: The process and network processes a mobility origination message, derives the subscriber's location and constructs a set of coupons or advertisements based on that location, for that subscriber, and at that particular time. The coupons or advertisements are then transmitted to the subscriber's handset. A retailer enters the various advertisements or coupons into the network for transmission to subscribers who call a predefined telephone number.

Abstract: A method of and system for processing calls to a wireless unit determines if the wireless unit is in a “page-only” mode or otherwise unavailable to receive the call. If said wireless unit is unavailable to receive the call, system determines if the calling party would like to send a page to the wireless unit. If so, the system sends a short message to the wireless unit. The short message identifies the calling party and provides an option to receive the call. When the wireless unit receives the short message page, the called party can elect to receive the call by sending short message response to the system. When the system receives the short message response, the system completes the call to said wireless unit if the short message response indicates selection of the option to receive the call.

Abstract: A powered wheel bearing has a solid spindle supported within a stationary hub by two rows of bearing balls. The innermost ball row has a separable race that is fixed in place by an abutting keeper ring that sits in an adjacent groove. The keeper ring, in turn, is prevented from dislodging by an overlaying shoulder on the sleeve of a CV joint that fits over the end of the spindle with interengaging splines. The joint sleeve is fixed to the spindle by an internal snap ring, so the motion of inserting the sleeve over the spindle is all that is necessary, both for attachment and alignment. The outside of the sleeve also carries regular teeth that provide the encoder ring for a speed sensor.

Abstract: A drip collector installed to a vehicle coolant pump of the type that has a protruding cylindrical bearing race with vent holes includes a feature to prevent collected coolant from splashing out, but not preventing it from collecting in the first instance. The collector includes at least one axially extending cylindrical sleeve that overlays the vent hole, with a small radial gap from the outside of the bearing race. Leaking coolant can run slowly through the gap, but cannot splash out quickly.

Abstract: A composite seal ring has a porous main body and a non-porous insert molded into it. Differential rates of coolant absorption between the porous main body and non-porous insert cause the whole ring to swell into a regular pattern of distortion. In order to compensate, the seal ring, after initial machining, is pre-soaked to simulate use and deliberately cause the same kind of distortion. It is then lapped flat from its distorted state.

Abstract: A pump drip collector is easily provided to a pump housing of a particular shape. A cylindrical drum of L-shaped cross section, incapable of serving as a drip collector by itself, is adapted to be freely pressed over a cylindrical protrusion from a flat face of the pump housing. When a circular end edge of the drum engages the face, it is spun welded in place. Thereafter, the drum and pump face together provide a complete drip collector. The drum may also pilot on the outside of the protrusion to maintain concentricity during the spinning process.

Abstract: A channel type vehicle water pump drip collector provides improved efficiency and capacity and a simple installation. The internal volume enclosed by a retainer that is snap fitted onto the housing is filled with an absorbent material. Leaking coolant is soaked up, rather than puddling at the bottom of the channel. Therefore, a leak proof, welded connection is not needed. In the embodiment disclosed, a retainer for the ring is attached by flexible teeth, and the spaces between the teeth provide air vents through which absorbed coolant may gradually evaporate to the outside.

Abstract: A vehicle water pump seal has a specially designed gasket interposed between the retainer flange that the spring bears on and the sealing ring that transmits the spring force evenly in spite of bowing in the retainer flange.

Abstract: A vehicle coolant pump is improved with the addition of a channel shaped shield that surrounds the coolant weep holes. In addition to protecting the weep holes, expelled coolant is collected and allowed to evaporate before it can visibly pond. The channel also serves as a convenient point for the provision of wrenching flats when the pump housing is also used as a belt tension adjuster.

Abstract: A slinger ring for a vehicle water pump shaft is given a scalloped outer lip, which causes the lip to undulate back and forth past vent holes in the bearing race as the pump shaft rotates. This provides a continual vent hole cleaning and scraping action.

Abstract: A water pump face seal assembly uses a wave spring stamped from flat stock with drive tabs which, besides providing contact force and wear take up, also serves to maintain a square, concentric contact interface and to transfer torque with almost no lost motion, isolating a joint between an elastomer seal and a seal casing from twisting stress.

Abstract: A vehicle water pump includes a unit handled assembly comprising a bearing housing, pump housing, and annular wear face sealing element, all made of suitable steels and alignable relative to one another at a common, accessible juncture of three circular edges. The components can thus all be welded together to give an easily handled unit, and the metal wear face has a much improved alignment, life and running temperature, as compared to a conventional ceramic wear face.
